Methane to methanol in supercritical water
(Elsevier, 1994-06)
We examined the feasibility of producing methanol from the partial oxidation of methane in near-critical and supercritical water. Oxygen was always the limiting reactant. The parameter space investigated experimentally ...
Research on dust explosions at the University of Michigan
(Elsevier, 1992-08)
Dust explosion research carried out at the University of Michigan during the last two decades has been summarized. Significant results are presented on the smoldering combustion of dust heaps, turbulent combustion of ...
Phase transformations of a liquid crystalline epoxy during curing
(Elsevier, 1994-06)
The phase transformations of a novel liquid crystalline epoxy, diglycidyl ether of 4,4'-dihydroxy-[alpha]-methylstilbene (DGEDHMS), from isotropic phase to liquid crystalline phase during curing have been studied using a ...
Solution and bulk properties of branched polyvinyl acetates : Part I: Non-Newtonian viscosity behaviour
(Elsevier, 1963)
A series of linear and branched fractions of polyvinyl acetate of relatively narrow molecular weight distribution was prepared and characterized by solution viscosity, hydrolysis, and light scattering measurements. At a ...
Interpretation of dynamic scattering experiments on ternary polymer mixtures
(Elsevier, 1992)
The dynamics of a ternary polymer mixture consisting of either homopolymers A and B, or diblock copolymers A-B, in a matrix of homopolymers C, is studied using the random phase approximation and assuming incompressibility. ...
Time–temperature superposition of large-strain shear properties of the ethylene–propylene copolymer system
(Wiley Subscription Services, Inc., A Wiley Company, 1972-02)
The principle of time temperature superposition for some mechanical properties of polymers is well known, particularly where strains are on the order of 1% or less. For large strains the simple data transformation techniques ...
Large volume, high-performance applications of fibers in civil engineering
(Wiley Periodicals, Inc., 2002-01-18)
This article presents an overview of fiber applications in cementitious composites. The socio-economic considerations surrounding materials development in civil engineering in general, and fiber reinforced cementitious ...
Positronium formation in semicrystalline poly(ethylene terephthalate)
(Elsevier, 1994-01)
The probability of positronium (Ps) formation in semicrystalline poly(ethylene terephthalate) (PET), has been investigated by means of positron annihilation lifetime spectroscopy (p.a.l.s.). The p.a.l.s. data are correlated ...
Effect of composition on molecular alignment in polyethylene terephthalate copolymers
(Elsevier, 1982-04)
In this study molecular alignment in copolymers of polyethylene terephthalate (PET) and p-hydroxybenzoic acid (PHB) was examined by means of differential radial distribution function (DRDF) analysis of wide angle X-ray ...
